RESILIENT GRIP.

Application filed April 19, 1923. Serial- No. 633,193.

To all whom it may concern Be it known that I, THOMAS EMIL GJoRUr, acitizen of the United States, and a resident of Chicago, in the countyof Cook and State .of Illinois, have invented a new and usefulImprovement in Resilient Grips, of which the following is a full, clear,and exact description. 1

My invention relates to improvements in resilient grips, and moreparticularly to resilient grips constructed of crude rubber,

or an unvulcanized rubber compound, and it consists in the combinations,constructions, and arrangements herein described and claimed.

An object of my invention is to provide a resilient grip of thecharacter described that is constructed of cohesive and elastic tapeadapted to be wound around the han Y dies of tools, oars, farm' andhousehold implements having handles, gripping members for supportingarticles, such as fishing rods, golf sticks, baseball bats, tennisrackets, and the like.

A further object of my invention is to provide a resilient grip of thecharacter described which because of the insulating qualities of thematerial, may also be employed as an insulating grip, suchasis desirablefor the handles of electricians pliers, control levers, and the like.

A further object of my invention is to provide a resilient grip of thecharacter described constructed of a rubber tape in which the frictionaland elastic nature of the material provides means whereby the tape mayadhere firmly to smooth surfaces, such as the varnished surface of agolf club handle or the like.

A further object of my invention is to rovide a resilient gripv in whichthe coesive and elastic properties of the tape employed provide for theuniting of the adjacent edges of the tape as it is wound about thehandle, and therefore provides a continuous and unbroken surface whichclosely conforms with the contour and configuration of the handle.

'A further object of my invention-is to provide a hand grip of.thecharacter described that is constructed of tape in which diagonalmarking lines are impressed or otherwise fixed upon the surface of thetape, whereby the tape may be cut so that the adjacent ends of a singlelength of tape the tape 1.

may meet uniformly as in the production of an endless-belt or band.

Other objects and advantages Wlll appear Figure 2 1s a sectional viewalong the line 22 of Figure 1,

Figure 3 is a view of a golf club handle upon which my improvedresilient grip is fixed, and

Figure 4 is a sectional view of a modified form of the tape illustratedin Figure 1.

In carrying out my invention, I provide a tape 1 constructed of cruderubber, or the crude rubber compound that has retained its cohesive andelastic properties. This tape is generally cut from smooth sheets,although crude rubber, known as crepe rubber, that is rubber having anuneven surface, may be used equally as well. 1 The tape 1 is cutapproximately one inch in width. (This dimension is purely optional.) 'Arelatively narrow band of rubber 2, cut from the same sheet as the bandsof tape 1, is securely fixed to the inner surface3of This may be done bylaying the band 2 longitudinally along the surface 3 and pressing theband 2 upon the band 1, or a cement may be employed, although it is notnecessary to use cement because of the extreme cohesive properties ofthe crude rubber. The band 2 is disposed at exactly the mid point of thetape 1 (see Flgure 2). A paraffinsheet 4 is employed between theadjacent layers of the tape 1 when it 1s packed in roll form, as shownin Figure 1. This is so that the layers will not adhere to one another,.and also to preserve the cohesive properties of the rubber.

From the foregoing descriptlon of the various parts of the device, theoperation thereof may be readily understood. The tape when applied to ahandle 5, or the like, to form my improved resilient grip, is woundaround the handle in a spiral manner, so that the ad'acent edges 6 ofthe spiral windin touc one another. These edges will unite due to the,cohesive property of the tape and therefore will provide a uniform andcontinuous surface. lhe tape 1 is wound around the handle 5 so that theband 2 is on the inside and therefore ribbed protrusions 7 will appearin spiral arrangement on the grip. There will be no sharp edges,however, due to the fact that the band 2 is on the inside, and that theband 1 is pressed downwardly thereby.

In applying the tape, it is absolutely essential that the tape bestretched slightly as it is wound about the handle 5 so that incontracting, it may adhere firmly to the surface of the handle.

The ends of the tape are cut diagonally along marking lines 8 providedon the outer surface of the tape, and the outer ends of the tape areplaced under the first and last windings, respectively, and by thismeans held against accidental unfastening.

In Figure 4- I have shown a modified form of the tape used in myimproved resilient hand grip in which in place of employing a band 2, 1construct the tape with its inner face 1 having an inwardly extendingintegral flange 2 thereupoln When the tape is constructed in thismanner, it may be forced through a die having the configuration of thecross section illustrated in Figure 4. The use of this modified form isprecisely the same as the use of the preferred form of the invention. Myresilient grip is particularly well adapted for supporting articles,such as fishing rods, golf clubs, tennis rackets, and the like, in whicha grip whichwill not adhere to the hand is most essential, but in whichthe entire frictional and resilient properties are necessary.

I claim:

The combination with a substantially cylindrical handle member of a tapehaving adhesive and elastic properties, said tape being provided with alongitudinally disposed, relatively flat rib on one side thereofextending continuously throughout the length of said tape, said tapebeing wrapped around said handle member in spiral fashion with said ribin contact with said handle whereby a grip having a spiral raisedportion is provided for said handle.
